The way the true use of anti-static products

    The anti - static products as ordinary products use a lot of companies to use as ordinary products, the product is not damaged can continue to use, in fact, this is a misunderstanding. For example, anti-static wrist strap is generally only a few months of life, when the use of a period of time after the appearance may not use damage, but with the use of anti-static wrist strap tester test will often find that the wrist strap has been broken.
    Don't pay attention to the shoe pad and socks
    People usually wear anti electrostatic shoes will wear socks or cushion insoles, foot sweat, these socks and insoles will therefore conducting electrostatic, but some of the foot is not easy to sweating people if you wear some do not prevent electrostatic due to sub and cushioned insole, the socks and insoles can't conducting electrostatic, the human body electrostatic cannot the shoes into the earth. Therefore, in the room or workshop at the entrance of the "human body integrated resistance tester", the human body comprehensive test instrument which can quickly and accurately detect those who wear the non qualified anti-static shoes, socks and pad pad. That workers wear anti-static slippers also don't wear due to sub in the summer, in the winter can wear socks but do not wear nylon socks.
    Ground connection method is not good
    A, anti-static system must have independent and reliable grounding device, grounding resistance should be less than 10 ohm, embedding and detection method should comply with requirements of GBJ 97.
    B, anti - static electricity can not be connected to the zero line of the power supply, and can not be shared with lightning. Because of lightning and other phenomena will affect the performance of the product and personal safety through the loop.
    C, the use of three-phase five wire power supply, its large ground wire can be used as anti - static ground (but the zero line, ground wire shall not be mixed).
    D, then the main trunk section area should not be less than 100mm2; branch dry line section area should not be less than 6mm2; equipment and working table of the ground wire should be used to cut the area is not less than 1.25mm2 of the multi shares deposited plastic wire, grounding wire color to yellow green line is appropriate.
    E, the connection of the main trunk route should be used in brazing.
    F, anti-static equipment connection terminal should ensure the reliable contact, easy assembly and disassembly, and allows the use of a variety of clip on connector, such as Ngok fish clip, a plug seat.
    G, the higher the value of the ground resistance of the workplace should be installed to monitor the ground system.
